I use google play music quite often and have enabled the built-in equalizer settings in the app. After the recent software update "JZO54K.I535VRBMD3" the volume level has reduced to almost half. I can regain the volume level if I disable equalizer in the google play music app. I don't want to disable the equalizer as I hate the flat sound. I have also tried another equalizer app "Equalizer". I see the same problem with this app as well. No equalizer settings applied, normal volume. Equalizer on, volume reduced to half. Any solution to this problem out there?
